Tv nu memoreaza nimic.Am schimbat memorie,procesor fara rezultat.Am probat cu un eprom cu programe memorate si le tine minte,dar nu se poate modifica nimic altceva,si nici in meniu service nu memoreaza setarile.A intalnit ceva defectul asta?

Nu am vazut urme de letcon pe acolo. Din cauza asta am fost nedumerit in privintza acelui scurt la rezistentza aia.Pana la stadiul asta am mai avut discutiii cu el:a avut scurt poarta sursa (circa 1k) la tranzistorul din sursa,si nu pornea decat cu mari rugamintzi si integratul final sunet ars.
